    I see no particular *technical* problem with using WJ, though. In
    to the suggestion of using CGJ (re. another problem) anywhere else but
    at the end of a combining sequence. CGJ has combining class 0, despite
    being invisible and not ("visually") interfering with any other
    mark. Using CGJ at a non-final position in a combining sequence puts
    in doubt the entire idea with combining classes and normal forms.
